IMPROVEMENT IN MACHINE FOR SIZING AND POLISHING BRAID.

TO ALL WIIOM IT MAY OONCERN: i

Be it known that I, JOHN S. FENNER, of Warren, in the county of Bristol, and State of Rhode Island, have invented certain new and useful Improvements in Machinery for Sizing and Polishing Braid; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specication, in Which- Figure I is an elevation of one side of the improved machine.

Figure 2 is a longitudinal section, taken in a vertical plane through the centre of the machine.

Figure 3 is.a transverse section, taken in a vertical plane through the centre of the machine.

Figure 4 is a side view of a reel-rack with a number of reels applied to it.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to certain novel improvements on machinery which is designed for sizing, smoothing, andrrprolishing braid, and giving to it a beautiful lustre and finish.

The nature of my invention consists inprovidng for sizing and polishing braid, on its way from one reel or series of reels to another, by conducting the -braid through a sizing-trough and between pressure-rollers, and then subjecting it repeatedly to the action of swiftly-revolving brushes, against which the braid is held by guide-rollers, arranged as will be hereinafter explained.

To enable others skilled in the art to understand my invention, I will describe its construction and operation.

Previous to my invention, machinery consisting chiedy of a series ot` revolving brush-cylinders has been employed, in conjunction with a sizing-trough, for the purpose of sizing, drying, and polishing sewing-thread, and in several machines for this purpose the thread is sized, dried, and polished on its way from one set or series of spools, bobbins, or reels to another., I do not, therefore, desire to be understood as claiming broadly the broad principle of treating thread as above mentioned.

'In the'accompanying drawings, A represents a frame, which is strongly constructed and braced, and adapted to serve as a substantial support for the brush-drums and the rollers, which guide the braid, andkeep it in close contact with said drums while passing through the machine. Near the base of this frame A, and supported by suitable boxes arranged in the centre of the frame, is the horizontal driving-shaft, B, which carries a cylinder or drum, C, having brushes, t, applied upon its periphery. Above this brush-drum C, and arranged in the same vertical plane, is another brush-carrying drum, D, which is fast upon a horizontal transverse shaft, D, and which receives rotation from the shaft B, through theA medium of a belt passing around belt-drums O1 Dzyshown in fig. 3.

On both sides of the vertical centre of the frame A, a number of guide-rollers are arranged, as shown in igs. 1 and 2, which are designed for carrying the braid over'and around the brush-drums, and holding it in close contact with these drums, while they are revolved very rapidly. The guide-rollersjj andthe guide-rollers c c are arranged in planes parallel to the axis of the brush-drum C, and are disposed about'this drum in such manner that the braid will be held in contact with the said cylinder, as shown in iig. 2, the red line indicating the braid, and the course it takes while passing through the machine from the reel E to the reel El.

Above the rollers c cf are rollers d d', rollers g g', and rollers 71. t, which are arranged in such relation to the brush-drum D, that they als hold the braid in close contact with the brushes, as shown in hg. 2. The rollers around which the braid iscarried are constructed with annular grooves in their surfaces, arranged close together, for the purpose of guiding each length of braid, and keeping it in proper place while being carried through the machine. The said rollers, with the exception of the intermediate rollers d d, are all rotated in the same direction by means of belts Vpassing around pulleys, which are applied to their ends, as indicated by blu-e lines in fig. 2. These rollers receive intermittent rotary movements from a belt-drum upon a shaft, J, on

kane end of which a spur-wheel, W, is keyed,'which wheel is acted upon and moved a certain distance, at every half` revolution of shaft B, by means of teeth w, upon this shaft, as shown in g. 1. Other meansthan that shown may be employed for communicating an intermittent feed-motion to the guide-rollers.

The shaft J also communicates an intermittent feed-motion to the reel El, upon which the braid is wound as it leaves the machine, by means of' a belt, which passes'around a pulley, k, upon ashaft, K, and another belt which communicates the movements of this shaft tothe said reel, by passing around a. grooved pulley on one side thereof.

` The braid-is carried from a reel, E, downward and beneath the rolls a a, which are applied in a trough, F, containing thesizing-solutiomand from this trough the braid passes between two rollers, F1 F2, which are supported by brackets G, that are secured to the frame A. The upper roller, F2, is acted upon by loaded arms f, so that, as the braid passes between this roller and its fellow, the superiluity of moisture is squeezed out of it and runs back into the trough F. From thepressure-rolle'rs the braidf'is carried beneath a roller, b, thence upward, and against the rollers c, d, g, t, and t; thence downward around the rollers g', d', c,.7", and j, and upward again, and so on it is carried several times around the two brush-drums, and it leavesthe roller c and is carried oiT and passed around the winding-up-reel El. A

It will be seen that each strand or length of braid, after leaving the squeezing-rollers, is carried against the guide and feed-rollers several times, so that a considerable length of braid will be passingthrough the machine at one time, and acted upon repeatedly by the brushes on the two brush-cylinders.' This arrangement of the guidejrolls and the braid upon them renders unnecessary the use of a great number of brush-cylinders,

as the same parts ofv tbe braid are subjected several times to each brush-cylinder, and to different -parts of the brushes on each cylinder.

In carrying the braid around the guide-rollers, I shall so arrange the several strands or lengths-that those parts of the'bra'id which contain the most moisture shall be nearest .reach other, thereby preventing the drier portions from being charged again with moisture by the brushes. It will also be seen that the braid is fed through the machine by intermittent movements, so that it will be held much longer in contact with the brushes than would be the case if it moved continually through the machine. And it will also be seen that the brushcylinders cannot throw oil` the braid by their rapid rotation, as ,thefeeding and guide-rollers above and 'below i each brush-cylinder are so arranged with Arelation thereto that the braid is held obliquely against the brushes.

In carrying out my invention, I shall construct the racks EXE2 with open receptacles or bearing-boxes, for receiving and allowing of the ready retrieval-of the reels, so that the filled reels can be taken directly from the braid-making machine, putupon the rack EX, and the braid carried through Vthe sizing and dressing-machine to the winding-up reelE, andl wound upon this reel as 'fast as vit is dressed.

Ioshall also lemploy racks, constructed substantially as shown ing. 4, with a. number of reels upon them, and arrange them at both ends of the machine, so that a number of separate strands or lengths can b e passed through the machine at one and the same time.

Each one of these racks consists of angular frame, N P, having open bearing-blocks, n, applied upon the inclined bar, P, so that, when the reels are in place, they will lie one above another, in diierent vertical planes.

Each wheel, r, has a grooved pulley, r, on one side, for receiving a driving-belt, and all the reels can be driven from a common drum.

When a reel or series ofreels has been' emptied or filled, as the case may be, it can be readily removed from its rack, and another reeLor series of reels substituted in its place.

Having described my invention, I claim, as improvements -in the treatment of braid, and desire to secure by Letters Patentv i y 1. The arrangement of driven, guide, and 'feed-rollers with a rotary brush or-brushes, such rollers presenting the braid to the brush or brushes, substantially in the manner shown and described, and so that the braid in passingthrough the machine shall be repeatedly subjected to the action of the brush or brushes, substantially as described. l i

2. The arrangement of guide and .tension-rollers jj', c c', qld', g g', and t 71.', upon opposite sides of brush drums C D, substantially in the manner and for the-purpose described.

3. In combination with adressing and polishing-machine, mechanism, substantially as herein described, for communicating an intermittent movement to the braid, while it is being acted upon by brushes, substantially as specied. i I l 4. The arrangementot` the weighted roller F2 and the roller F, with a sizing-trough and drying and dressingbrushes, as described.l i Y i 5. The arrangement of the guide and tension-rollers odg with the brushes C D, substantially in the manner described.v Y

6. 'lhe combination of the reel E, sizing-trough F, brushes C D, guide and-tension-rollers y', c, d, g, and h, and reel E, all arranged substantially as described.
